Surveying Caribbean Cultural Landscapes: Mount Plantation, Barbados, and its global connections

open access: yesInternet Archaeology, 2013
The first systematic archaeological investigation on Barbados since the 1970s at Mount Plantation, St George, Barbados, has yielded significant material and landscape data relating to world-changing economic and social structures, from the dramatic early

Anwendung der NMR-Spektroskopie chiraler Assoziate 5: Chirale Butadiene 7: Stereodynamics and Diastereotopism in Chiral 1,3-Dienes HOCMe₂-(-CC1=CC1-)-₂R

open access: yes, 1978
The barriers to partial rotation around the central single bond in chiral dienes HOCMe₂-(-CC1=CC1-)-₂R have been determined by coalescence of either 1H NMR signals (X = CH2OCH3) or 13C NMR signals (X = H).

The different photoisomerization efficiency of Azobenzene in the lowest nπ* and ππ* singlets: the role of a phantom state

open access: yes, 2008
Azobenzene EZ photoisomerization, following excitation to the bright S(ππ*) state, is investigated by means of ab initio CASSCF optimizations and perturbative CASPT2 corrections.

The INDO/2-AHP method for excited states : Part 2. The adiabatic proton affinities of formaldehyde in 1,3nπ∗ and 1,3ππ∗ states

open access: yes, 1982
The gas-phase proton affinities (PA) of formaldehyde in the nπ∗ and ππ∗ states have been studied theoretically using the average hole potential (AHP) model at the INDO/2 level of approximation.

(a) Confocal fluorescence microscopy images of nonfixed spindles assembled either in the absence or additional presence of p50 or cc1 showing the localization of Eg5

open access: yes, 2011
The fluorescence of Eg5-paGFP (green) and of Cy5 microtubules (MT; red) was measured immediately after photoactivation of Eg5-paGFP in the entire spindle.

Determination of T→KππνT weak decay structure functions from current algebra

open access: yes, 1980
T→Kππντ decay form factors are considered within the framework of current algebra. Explicit momentum dependence of the form factors has been used to obtain the branching ratios of τ→Kππντ to τ&
